DISTRIBUTING BUCKET FOR CONCRETE PAVERS.

Application led April 2,

To (1U `11g/Loin. 'it muy conce/'12 le it known that l, CuAnLi-s E. Foo'rn, a

citizen o f the United States, residing at hunde, lin the county of Livingston and 5 teinte of New York, have invented certain new and useful improvements in Distributing Buckets for Concrete Pavers, of which the following is a speciiication. n My invention relates to new and useful improvements in distributing' buckets for concrete pavers and is a companion of an application filed by me on March 80, i925, bearing Serial Number 19,23%?.

The present invention relates to a distributing bucket having pivotal bottom doors, a trolley for supportingl the bucket in its to and fro movement on a boom, a cross shaft on the trolley, a tripping mechanism in the 'form of a segment mounted on this shaft, a nd means extendiiii,r from the bucket doors to this shaft so that a rocking` of the shaft by this segment will cause the doors to open and close as desired.

The invention is an improvement on the bucket shown in the patent granted to me on January 30, i923, No. lf'rillei.

The operation of the segment in the preseut invention is similar to the mode of operation shown in the above mentioned patent, that is, there is a cable secured to Athe opposite ends of the segment and to a drum so that a stopping of the drum as the bucket 'moves along` the boom will cause the sonk ment to partly revolve and thereby open or close the doors; but instead of mounting the segment only on the cross shaft and providingl an arm in the form of a lvoke connected to the segment, and instead of providing a cross head and side members as shown in my previous patent, I extend the length of the shaft and mount the segment thereon, and also provide two short stub arms on the shaft to which in turn are secured side members that extend downwardly of the sides of the bucket and are secured to the doors. Spring means, however, are interposed in the side members so that the doors will be resiliently held in their closed position.

"to 'In a number of forms of buckets new in use, spring means are interposed between the tripping mechanism and a yoke or side members which entend to the opposite ends of the door or doors, and if there is any sagging, the door or doors will, sag as a Cil 1925. Serial No. 20,142.

whole throughout their length. lVith my constructhm about to be described, should any concrete stick between the bucket and the doors, one end may sag slightly without affecting the other end and the offending material may be quickly removed and the door made to assume its proper position.

In the present invention also, l do a "ay with' a cross head or an extra shaft as shown in a numberI of forms of buckets, and mount the side membersof the doors directly upon the shaft which supports the segment, thus providing' a more economical construction, and also makinp,` it easy to trip the shaft by a hand lever when desired, which was practically impossible with my old style bucket.

@ne of the objects, therefore, of the present invention, is to provide a bucket supported by a trolley adapted to move to and fro on a boom, the trolley having a single central cross shaft on which is mounted a segment and from which shaft extends the side members down along,` the sides of the bucket to the doors, the side members having incorporated therein springs to add a resilient action to the closing' and supportingr of the doors.

Still another object of the invention is to provide a bucket which may be readily tripped. by a hand lever, readily tripped by :i cable as shown in my previous patent, and also tripped automatically by means at the inner end of the boom so that the doors of the bucket will always be closed when the bucket is in position to receive the aggregates.

vWith these and other objects in view, the invention consists in certain new and novel constructions and combination of parts will be hereinafter more fully described and pointed out in the claims.

Referring now to the drawings showing a preferred embodiment of, my invention,

Fig. l is a side elevation showing` a tragmentary portion of a paver having a boom extending' therefrom and on which is shown my improved bucket, the doors being shown in their open position, the dotted lines showing the bucket approaching the inner end of the boom to be automatically tripped, so that the doors will be in their closed position when the bucket is at the inner end of the boom.

Fig. 2 isan end view of my improved bucket, showing the manner of supporting and operating the doors, and

Fig. 3 is a side elevation of my improved bucket with the doors shown in their closed position.

Referring now more in detail to Fig. 1, there is fragmentarily shown a portion of a paver comprising an upright 1, a portion of a frame 2, a small platform 3, and a lower platform 4, while mounted on this lower platform 4 and arranged for hori- Zontal movement as well as vertical adjustment, is a boom 5, similar to the boom shown in my patent of January 30, 1923, No. 1,- 443,354, and similar to the boom shown in the application filed by me on March 30, 1925, bearing Serial No. 19,342.

Located on this boom 5 is a trolley7 6 to which is secured a bucket 7 by the straps 3. Secured to the opposite end of the trolley (i are the ends of the cable 9 which cable extends under sheaves 10 and upwardly over sheaves 11 where the cable then passes over and under, and is secured to a drum 12 shown in dotted lines, which drum is mounted on the platform 3.

This drum and its mode of operation form the subject matter of the aforementioned application, Serial No. 19,342. The purpose of this drum and cable is to drive the bucket to and fro on the boom 5, while a second drum 13 is secured on the boom, as shown in my previous patent, over which passes a cable 14, which cable in turn is secured to and passes over a trip member in the form of a segment 15, which segment is mounted on a cross shaft 16, which in turn is mounted in the trolley G. Supporting` means extend from this shaft down to the doors of the bucket, as will shortly be described, and it will be understood that a tripping of Jthis segment land a rocking of its shaft, will open and close the doors.

A brake band 17 is shown in Fig. 1 in dotted lines, as being applied to this drum, the brake band in turn heilig fastened to a suitably mounted bell crank 1S so that an operation of this bell crank 18 by the rope 19 will apply the brake to the drum 13, and as the bucket moves along the boom, it being driven by the drum 12, and the drum 13 being vstopped in its rotation as the bucket continues to travel, the segment will be partly revolved and the doors opened, all of which -will be clearly understood by referring to my patent above mentioned.

In my previous patent I showed the brake band connected to the drum being operated by Va foot pedal, whereas in the present application, have shown the brake band applied by the operation of a rope extending` over tothe `platform on which the opel ator stands.

In the present application also, I have provided an automatic means fer applyin a braking pressure to this drum, which cousists of extending a rod 2O through an eyelet 21 formed in the bell crank 18 and on the inner end of the rod are two bolts 22, while the outer end of the rod is secured to a trip arm 23 that is pivoted as at 24 on the boom 5, this arm having' a roller at its lower end adapted to contact with a plate 25 mounted on the trolley 6, so that when this trolley 6 approaches the inner end of the boom it will trip the arm and through the rod 2O and the bell crank 13 apply the brake to the drum 13, causing the segment to return to its normal position, thus assuring that the doors will be closed.

By providing the bell crank 1S with the eyelet 21, the rod 2O will simply work through the eyelet as the bucket mores outwardly so that no pressure will be applied to the drum nor will the segment be tripped, as the bucket starts outwardly,

So far as the invention has been described, it follows closely the invention shown in my previous patent, with the exception of the L automatic tripping means.

Referring now more specifically to the manner of supporting and locking the doors of the bucket referred to and the tripping i'nechanism, and glancing at Fig. 2, there is shown the shaft 16 which is suitably mounted in the plates 2G of the trolley This shaft is much greater in length than shown in my previous patent, and near its outer end and beyond the sides of the plates, are the stub arms 27, while mounted between the plates on the shaft is the segment 15 heretofore referred to. Secured to these stub arms 27 are the side members or arms 28, these arms 28 being slightly offset at their upper end as at 29 where they are secured to the stub arms 27. These arms or side members 28 are curved or deflected as at 29 and have their' ends 30 bent outwardly as clearly shown in Fig. 2.

Extending respectively through the ends 30 are the bolts 31 of the couplers 32, and secured in the lower ends of each coupler are the upper ends of the rods 33, which rods extend downwardly and are pivotally connected at the lower ends to the ends of the doors 34, which doors are pivotally mounted as at in the opposite sides of the bucket, and extend across the same.

Resting onthe ends 30 of each side member 28, and about the bolts 31 of the coup lers 32, are shown the springs 36 secured by the bolts 37 so that the weight of the coors are transmitted to the springs 36, thus providing a resilient action for the closing of the doors. Each end of the Arespective doors is -therefore resiliently held, which is an advantage, as in case of any sagging or jam between the doors and the bottom of the bucket, one end of door may sag rather llll fill

than the door as a. whole sag, which is the l.ase in many of the different types of bucket new in use.

On one end of the shaft 16 there is shown a handle 38 which .makes it possible to rook this shaft 16 by hand te thereby open er close the doors and as Ythe force from `the handle is transmitted directly to this shaft le', it is possible te open and Close the doors with Comparative ease, which. was not pos- Isible with my previous style of bucket, except with great exertion.

The operation. of the bueketand its doers comparatively simple, and it will be readil;Y understood that when the segment is in the position shown in Fig. 3, the side members, stub arms and cross shaft ferm a toggle arrangen'lent, thus securely holdinga 'the doors in their closed position, while a rocking' of this segment reeks the shaft 16, and the side members connected to the doors are directly connected by stub arms on this shaft, a rocking,` of the shaft will brezl the toggle and allow the doors te open or vice versa.

Furthermore, by providing spring means within the side l'llembers, there will be a resilient- :ietion in the opening' and closing,` of the doors, and each end. will be resiliently supported.

.flgaiin it will be unl'lerlzltood that the doors may be opened by rocking the shaft llianullly by the handle 38, that the seglllent may be operated by applying the brake on the drinn 13 to thereby trip the doors as (he boeket moves, and lastly the seglllents and its shaft will be tripped by the plate contacting with the arlll 23 and applying` the brake to the drum to elose the doors should they happen to be opened, as the trolley and bueket approach the inner end of the boom.

.llrelll the foreigningv it will be seen tha.. hy nleul'lting a eross shaft in a trolley and. extendingj` the side nlen'lbers which are eon nected to the doers up to this cross shaft, I have done away with extra shafts and yokes and rods sueh as shown in my prerious patent, thus cutting,- down the expense of the construetion, and furthermore l have made it possible to open these doors manually as the torce will. be transll'litted directly to the shaft 16; also l have made it possible to resiliently support the respective ends of each door which. is an inlproven'lent over simply resiliently supporting the doors as a whole.

litany slight changes might be made without in any way departing from the spirit and scope of the invention.
